"Megumin has just arrived in Axel, and she's got a devil to defeat! Rumors abound of a powerful Arch-priest well versed in exorcism, and our resident Explosion expert intends to track her down! Meanwhile, Yunyun renews her desperate search for friends, but she's getting nowhere fast . . . It's the end of the beginning for these Crimson Magic adventures as 'Konosuba: An Explosion on This Wonderful World' comes to a fiery conclusion!"--Back cover.

"One year before a certain useless goddess and NEET extraordinaire hit the scene, Megumin, the 'Greatest Genius of the Crimson Magic Clan,' is hard at work. Ever since a life-changing encounter in her youth, the young wizard has dedicated her every waking moment to the pursuit of the ultimate offensive magic, Explosion! (Well...every moment not spent hustling food from her self-proclaimed rival.) And while the big sister's away, the little one will play. On a routine trip into the woods, Megumin's little sister, Komekko, finds a strange black kitten. Little does she know that this cat plays a key role in unsealing a Dark God's tomb"--Back cover.

"Leaving Arcanletia and the Axis Church behind, Megumin and Yunyun hop on a wagon bound for Axel, where Megumin's role model awaits. It's going to be an even rougher ride than they expected however, when monsters assault then at every turn! Is this just bad luck, or is there something more sinister at play...?"--Back cover.

"Secret Society Kusaragi's on a mission to conquer the world, one lewd remark at a time. With a garbage reputation and a knack for trash talking, these guys are hardly the elite force needed for an invasion, but for something as insane as world domination? Maybe"--.
